Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter

A cabsim is theoretically designed to mimic the EQ response of a guitar cabinet, so I'd say yes, it replaces the need for a cab impulse response (unless you wanna go Scholz on your guitar sound :)).

As for the 1st question, if I wanted to add a balanced output, I'd probably check the H&K Red Box schematic and try to adapt it to this one... Or build the GGG passive direct box in the same enclosure.

For the red box: https://effectslayouts.blogspot.com/2018/10/hughes-kettner-red-box-mk-ii.html?showComment=1540468734020#c7991046569522358586or the source:https://i.postimg.cc/TwnqbWnb/H-K-Red-Box-2-schem.png

I got this one on my breadboard in a working state. I think the mids should me A10k and not A100k. Also I think that the gainpot pinout is reversed (yes it is conform schematic, but I think there is a mistake there). I am still experimenting as I am not familiar with this effect and I am not sure it is working 100%. I will report back as soon as I A/B it with the videos that are online.

For clarification, in the schematic the circle on the pots indicates Pin 3 (CW) so they are correct now. I learned that the dot/circle indicates Pin 3 but that could very likely have been wrong (and why i usually use numbers but EasyEDA doesn't have a numbered symbol).

Also - in the original Mids is definitely 10kA. It may well sound better as 100k (I've taken it off the breadboard now) but the original is 10k.

yep verified. Although I think we still need to see if the schematic is really correct. It sucks a lot of distortion/overdrive out of highly distorted/overdriven sounds. If you put a angry charlie in front of it if takes out really a lot of overdrive. @Robert Burton aka bobbass4k, do you have any pedal gutshots left to double check the values? I am willing (and hopefully able) to help!

Interestingly, I had the same thing with a number of cabsims that I've build over the last couple of years.

The Marshall cabsim over at Sabrotone that I requested nerfs the distortion quite a bit for some reason, but not as much as Joe Davisson's Cabsim. Lart's Simple Cabsim is the best one I've found so far (and actually sounds great).

The Marshall 3005 Lead 12 was a mini-stack with a 12 watt solid state head made in England between 1988 and 1991. People claim it's a gr...
